Journal ArticleDOI
Ultra-wide-band tellurite-based fiber Raman amplifier
TL;DR: In this article, the authors proposed a wide-band tellurite-based fiber Raman amplifier (T-FRA) for seamless ultra-large-capacity dense wavelength-division multiplexing (WDM) systems.
Journal ArticleDOI
Guided-wave laser based on erbium-doped silica planar lightwave circuit
TL;DR: In this paper, the Er-doped silica guided-wave laser operating around 1.6 μm was realized using a low-scattering-loss planar lightwave circuit with an Erdoped Silica core which was fabricated by flame hydrolysis deposition and reactive ion etching techniques on an Si substrate.
Journal ArticleDOI
Fluoride-based erbium-doped fiber amplifier with inherently flat gain spectrum
Makoto Yamada,Terutoshi Kanamori,Yukio Terunuma,Kiyoshi Oikawa,Shimizu Makoto,Shoichi Sudo,K. Sagawa +6 more
TL;DR: In this paper, an average signal gain of 26 dB was achieved for 8-channel WDM signals in the 1532-1560 nm wavelength region with a gain excursion of less than 1.5 dB at an input signal power of -20 dBm per channel.
Journal ArticleDOI
1.58-/spl mu/m broad-band erbium-doped tellurite fiber amplifier
A. Mori,Tadashi Sakamoto,Koichi Kobayashi,K. Shikano,Kiyoshi Oikawa,K. Hoshino,Terutoshi Kanamori,Yasutake Ohishi,Shimizu Makoto +8 more
TL;DR: In this article, a 1.58/spl mu/m broadband and gain-flattened erbium-doped tellurite fiber amplifier (EDTFA) was proposed.
Journal ArticleDOI
S-band erbium-doped fiber amplifiers with a multistage configuration /sub e/sign, characterization, and gain tilt compensation
TL;DR: In this article, an S-band erbium-doped fiber amplifier (EDFA) with a multistage configuration is presented, and the authors show that there is a tradeoff between low noise and efficiency.
